Why this study deserves your click Every ARDS patient forces us to answer the same question: “How much PEEP is enough—and how much is too much?” We usually lean on ARDSNet tables, “PEEP ladders,” or our own bias. This trial asks a different question: What happens if we let the lung tell us the right […]
Abstract This physiological study evaluated how ascending PEEP titration (0 → 4 → 8 → 12 → 16 cmH₂O) alters respiratory mechanics and mechanical power (MP) in deeply sedated adults without lung injury. Key findings show that increasing PEEP consistently and significantly raises: Total mechanical power Plateau pressure Static elastic power Total elastic workload …while
Summary This prospective observational study compared the physiological effects of three different positive end-expiratory pressure (PEEP) titration strategies in patients with acute respiratory distress syndrome (ARDS): a driving pressure-based clinical approach, an empirical oxygenation-based method (high PEEP/FiO₂ table), and fixed PEEP levels (5 or 15 cmH₂O) determined by ARDS severity. Findings revealed that clinical titration
Abstract Patients in critical condition who require mechanical ventilation experience intricate interactions between their respiratory and cardiovascular systems. These complex interactions are crucial for clinicians to understand as they can significantly influence therapeutic decisions and patient outcomes. A deep understanding of heart–lung interactions is essential, particularly under the stress of mechanical ventilation, where the right
Positive end-expiratory pressure (PEEP) has been interwoven with acute respiratory distress syndrome (ARDS) since its first description by Ashbaugh et al. [1]. Thereafter, the potentially competing effects of PEEP on lung volume, gas-exchange, and hemodynamics were quickly recognized, prompting the first proposals for methods to optimize PEEP in the clinical setting. Eight years after the

Summary of “Assessing lung recruitability: does it help with PEEP settings?” This editorial examines the relationship between lung recruitability and the selection of positive end-expiratory pressure (PEEP) settings in acute respiratory distress syndrome (ARDS) management. While recruitability measures the potential to reinflate atelectatic lung regions, PEEP must prevent their collapse while considering additional factors like
